Desulphation
The Desulphation stage may break down sulphation that occurs in batteries that
have been left flat for extended periods of time, returning them back to full charge.
sulphation occurs when lead-sulphate hardens and clogs up the battery cells.
Soft Start
A preliminary charge processes that gently introduces power to the battery. This
protects the battery and increases battery life.
Bulk (Constant Current)
Bulk mode charges the battery at the maximum rate (constant current) putting a
large amount of power into the battery in a short amount of time. This stage will
charge the battery to approximately 80%, until the voltage reaches 14.4 volts for
12V charger or 28.8 volts for 24V charger.
Bulk mode for the charging cycle. The start phase continues until the battery's
terminal voltage has risen above the set limit, at which point the charger
switches to bulk charging. If the terminal voltage has not passed the voltage
limit within the time limit, the charger switches to fault mode (lamp ③ solid) and
discontinues the charging. If so, the battery is faulty or its capacity is too large.
Absorption (Constant Voltage)
The charge rate slows down so the battery can absorb more power and reach
100% charge. The voltage remains at a constant 14.4 volts for 12V charger or
28.8 volts for 24V charge while the current is gradually reduced until no more
power can be added without over-charging the battery.
